A retraction device for movable furniture parts has a driver movable along a first guide path, which is movable between a retracted position and a parked position and is directly or indirectly pretensioned into the retracted position by an energy storage device. The driver can be coupled to an activator in order to move the movable furniture part into a closed position. A method uses the driver for opening and closing the movable furniture part and tensioning and releasing a retraction device.

A device for fixing a push element, in particular a drawer box to a rail of a pull-out guide, the device comprising a clamping mechanism with a receptacle for a holding part and a device for depth adjustment for the drawer box, wherein the device for depth adjustment comprises a stop that can be adjusted either on or in the receptacle. As a result, a precise orientation of the drawer box to a pull-out guide can be achieved using simple means.

Device and method for fixing a push element

A device for fixing a push element, in particular a drawer box to a rail of a pull-out guide, the device comprising a clamping mechanism with a receptacle, into which a web-shaped holding part can be inserted, wherein a self-locking clamping element is provided at the receptacle, by means of which the holding part is secured in a clamping manner against being pulled out. As a result, a particularly stable fixation of the drawer box to a pull-out guide can be achieved.

A device () for reducing noise levels in passenger conveyor systems () at least partially obstructs spacing () at the interface between two steps () to allow for relative movement between one step and the next. A sound transmission reducing member () at least partially obstructs a sound pathway that includes the spacing to reduce the transmission of noise through the spacing. The sound transmission reducing member in one example is a barrier that partially blocks the interface, while in another, it extends completely across the interface. Additionally, sound absorbing material () may be secured to the underside of the steps in order to further reduce sound transmission toward the passengers and individuals near the conveyer.

An escalator handrail drive arrangement includes a drive belt () mounted within a drive housing (). Pressure rollers () are mounted in pairs and pivotally attached to the drive housing. The pressure rollers bias a handrail () against the drive belt. The pressure roller arrangements are mounted at each axial end. A spring () biases the pressure roller arrangements against the handrail, with the spring being centered along the axial length of the pressure rollers. This spring is preferably mounted within the drive housing such that no additional space is required outwardly of the drive and roller arrangement to accommodate the spring.

Method for compensating the length of a movable handrail () in a passenger conveyor () having a passenger transportation belt () defining at least one passenger transportation surface (), the handrail () is traveling along a closed handrail path which extends through an exposed path () along the passenger transportation belt (), around a turnaround means (), through a return path () and around a further turnaround means (), and which hand rail path defines a handrail plane which is substantially perpendicular to the passenger transportation surface, the method comprising the following steps: (i) turning the handrail () out of the handrail plane; (ii) directing the handrail () through a compensation means (); and (iii) turning the handrail () back into the handrail plane.

Handrail compensation device

A passenger conveyor handrail () has a gripping surface () with a generally circular cross-section. Disclosed examples include a toothed driven surface () that is adapted to be engaged by a toothed driving member () for propelling the handrail in a desired direction. Disclosed examples include having the generally circular cross-section extend along an entire length of the handrail () corresponding to the closed loop path followed by the handrail during operation of a corresponding passenger conveyor.

People mover () comprising an endless tread belt () formed from several tread elements () connected to one another, which is driven by a drive unit about a first and second reversal point (), and a side skirt () moved along with tread belt (), the side skirt () comprising flange elements () joined to the tread element () and bridge elements () connected movably relative to flange elements (). A sensor () is arranged adjacent to the side skirt (), the sensor () having a limited detection range perpendicular to the circulation direction of side skirt (), and a plurality of marking elements are arranged in a line on side skirt () along the circulating direction having a limited width perpendicular to the circulating direction.

Safety monitoring system for a people conveyor

A passenger conveyor handrail () includes a plurality of teeth () that interact with a toothed driving member (). In a disclosed example, a low friction material () is placed near an end of the teeth () on the handrail (). The low friction material () facilitates the teeth sliding along a guidance () but does not interfere with a desired engagement between the teeth() and corresponding teeth () on the driving member ().

A passenger conveyor including an endless conveyor band having a plurality of tread elements connected to and driven by a drive chain at each lateral edge thereof and a moving flange moving in use together with the conveyor band. The moving flange includes a plurality of discs attached to the tread elements and a plurality of bridges each attached between two consecutive discs. At least one bridge is attached to the drive chain by a pin and socket connection and a resilient locking element is arranged so as to bias in use the bridge against the chain.

Moving flange fastening for passenger conveyors

People conveyor () including an endless conveyor band () extending through an inclined portion (), a first and a second turnaround portions () and a return portion () of an endless path and comprising a plurality of steps () connected to and driven by a step chain (), the steps () comprising a step roller (), the people conveyor () further including a step roller track () for guiding the step roller (), the step roller track () extends along the path of the conveyor band () and has an inner and an outer rails () for supporting the step roller (), and a device () for restraining the step roller () against one of the inner and outer rails ().

Device for restraining the rise of a step roller of a people conveyor

The invention pertains to an escalator () with an endless stair band () that is composed of several interconnected steps (), wherein a step () contains a walking surface () and a front side () and is connected to respective lateral step chains () that are driven around a lower and an upper reversing point () by means of a drive, and wherein a step () contains at least one step roller () that is guided by a step roller guide. The invention is characterized by the fact that the point () at which a step () is fastened to the step chain () is arranged in the vicinity of the front side () of the step ().
